EPHRAIM BUTTERFIELD, OF \VRIGHTS CORNERS, INDIANA, ASSIGNOR TO THE IVHITMAN AGRICULTURAL COMPANY, OF ST. LOUIS, MISSOURI.

BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 362,875, dated May 10, 1887.

Application filed October 28,1886. Serial No. 217,418.

To all whom, it may concern:

Be it known that I, ErnRAnr BUTTERFIELD, of Vrights Corners, in the county of Dearborn and State of Indiana, have invented a certain new and useful Improvement in Baling- Presses,'of which the fOllOWing is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of thisspecifieation, and in which-- Figure 1 is a top view of part of a balingpress illustrating my invention. Fig. 2 is a detail vertical horizontal section taken on line 2 2, Fig. 3. Fig. 3 is a vertical section taken on line 3 3, Fig. 1. Fig. at is a detail View [5 showing the inner end of the sweep. Fig. 5 is an enlarged detail section of the rack and the lever in elevation for operating and holding the friction-shoes, this section being taken on line 5 5, Fig. 1.

My invention relates to a device for retarding the backward movement of the traverser or plunger of a baling-press, and my description will be confined to this part of the press, although other features which have no conneetion with my invention are shown in the drawings.

My invention consists in features of novelty, hereinafter fully described, and-pointed out in the claims.

Referring to the drawings, A represents the body, 13 the traverser, O the sweep, and D the connection between the sweep and traverser, all of which may be made of any well-known construction, and I claim no invention, per 80, therein.

It is well known that in this form of balingpresses the traverser or plunger, when the pressing is completed, is thrown back by the elasticity of the material being baled, and to 4 prevent it from being thrown back too freely different devices haveheretofore been adopted. My invention relates to a device for accomplishing this purpose, and consists in shoes yieldingly held in place near the outer end of thetraverser-chamber. As here shown,shoes or blocks E are hinged to the frame of the press at the outer end of the traverserchamher, and which may be moved inward, as shown by dotted lines in Fig. 2, into the trav- 5o erser -chamber to receive the impact of the (No model.)

traverser, and by friction resist or retard the backward movement of the traverser. The free ends of the shoes are provided with socketed pieces G, against which bear rods H, hinged at I to the frame of the press, and extending upward through slotted guide-plates J, secured to the top of the press. Fitting on the upper ends of these rods are plates or links L, the inner ends of which are connected to a tightener, M, consisting of a lever provided with a handle, N. The lever is pivoted at O to a cross-piece, P, of the press, and it will be seen that as the handle N is moved in the direction shown by the arrow in Fig. 1 the upper ends of the rods H will be moved to- 6 ward each other from the position shown in Fig. 3 toward the position shown by dotted lines in Fig. 3. As this movement takes place the shoes ID are caused to enter the traverserchamber, and they may be moved inward more or less to give greater or less resistance to the backward movement of the travcrser. They are held to given adjustments by a pin, T, on

a spring-latch, U, pivoted to the outer end of the handle N, the pin entering perforations or holes V in a rack or bar, XV. An enlarged View of the spring-catch, pin, rack, and outer end of the handle is shown in Fig. 5.

It will be seen that the bearing-point be tween the shoes and the rods If is at a point near the pivots I of the rods, so that a con siderable purchase is given the rods and tightener in holding the shoes to their adjustment.

A device thus constructed is cheap and durable and effectually performs the function 8 5 for which it is intended.

I claim as my invention- 1. In a baling-press, the combination, with shoes pivoted at one end to the frame at the outer end of the traverscr-chamber, of an ad- 0 justing device adapted to bear on the free ends of the shoes for holding them yieldingly in place for retarding the backward movement of the traverser, as set forth.

2. In a balingpress, in combination with 9 5 the shoes, yieldingly held in place, for retarding the backward movement of the traverser, mechanism for operating the shoes, consisting of hinged rods and a tightener connected to the upper end of the rods, substantially as set forth. IOO

3. In a baling-press, in combination with the shoes, yieldingly held in place, for retarding the backward movement of the traverser, mechanism for adjusting the shoes, consisting of hinged rods, a tightener connected to the rods and composed of a lever provided with a handle, and links connecting the lever with the rods, substantially as setforth.

4:. In a baling-press, in combination with the shoes, yieldingly held in place, for retarding the backward movement of the traverser,

mechanism for operating the shoes, consisting of hinged rods, links connected to the free ends of the rods, a pivoted lever to which the inner endsof the links are connected, a handle on said lever, a spring-catch provided with a pin on said handle, and perforated rack, with which the pin on the catch engages, substantially as and for the purpose set forth.

5. In a billing-press, in combination with 20 the shoes, yieldinglyheld in place, for retarding the backward movement of the traverser, and socketed pieces G on the shoes, hinged rods bearing against the soeketed pieces of the i shoes, slotted guide-plates J, through which 25 the rods pass, links connected to the upper ends of the rods, and a tightener to which the inner ends of the links are connected, substantially as andvfor the purpose set forth.
